Completed a commercial rooftop HVAC repair on a Trane packaged rooftop unit serving Coast To Coast Distribution in Austin, Texas. The customer reported the RTU was not cooling properly. Our technician returned with the required OEM replacement parts, including a liquid line filter drier, condenser fan motor capacitor, and new air filters. The sealed refrigeration system was opened, the existing liquid line filter drier was replaced, and the system was evacuated to a deep vacuum to remove moisture and non-condensable gases before being recharged to the manufacturer's factory refrigerant specifications. Additional preventive maintenance included cleaning both the condenser and evaporator coils, replacing eight air filters, clearing the condensate drain line, inspecting the blower belt, and replacing a weak condenser fan motor capacitor. Final operating pressures, compressor amperage, airflow, and condensate drainage were verified before leaving the site. The rooftop unit was restored to normal cooling operation and was operating within manufacturer specifications at the completion of service.
